APPARATUS FOR GENERATING GAS FROM PETROLEUM-OIL.

SPECIFICATION forming part of Letters Patent No. 407,267, dated July 16,1889 Application filed January 12, 1889- Serial No. 296,008. (No model.)

To all whom itmay concern.-

Be it known that I, AUGUST IVEYER, of Tallapoosa, in the county ofHaralson and State of Georgia, and a citizen of the United States, haveinvented certain new and useful Improvements in Apparatus for GeneratingGas from Petroleum-Oil; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon,which form a part of thisspecification.

This invention has for its object the furnishing of apparatus for theeconomical manufacture of gas from petroleum or other oils; and itconsists of improved construction of parts whereby such end is attained.

The details of the invention are hereinafter fully described, and thepart claimed as new pointed out in the claim.,

In the accoi'npanying drawings, Figure 1 shows the retort in sideelevation,showingits form and exterior appearance. Fig. 2 is a plan ofthe interior of the bottom half of the retort. Fig. 3 is a centralvertical section through the part A, showing the false bottom and thebricks thereon,and the means by which they may be removed.

In these figures like reference-marks indicate corresponding parts inthe several views.

The retort, composed of the parts A and B,

rests on the furnace O, of any suitable con-.

struction. The part A of the retort is hemispherical and detachable fromthe part B, in

order that it may be easily removed and renewed as soon as itis burnedso much as to require a renewal of saidpart. It will be seen that bythis novel construction of the retort the part A may be removed andanother replaced without disconnecting the pipes for need never bereplaced in repairiugis a matter of considerable importance as regardseconomy in apparatus.

On the bottom of the part A is the false bottom or pan J, which ispreferably of the shape shown, upon and around which are placed thebricks K. The oil on being discharged from the supplypipe will falldirectly on these bricks and spread over their surfaces. The bricks thatare nearer the bottom being hotter than those above, the oil isgradually heated to the point of decomposition, and as it runs downtheir surfaces and is being heated gradually to that point, it depositsall of the viscous residuum on the bricks, excepting a very small part,which is deposited on the bottom of the retort. The forming of a coatingof this residuum,which is produced in the manufacture of gas from alloils generally used for that purpose, is a great impediment to theefficacy of oil-retorts as heretofore used. The residuum causes thebricks to adhere to each other, but'causes no disadvantage to theoperation of the apparatus only in proportion as it fillsgtheinterstices between the said bricks after the said interstices havebecome as small as will permit the proper distribution of therequiredquantity of oil. The residuum will not, however, cause theadherence of the false bottom and bricks to the bottom of the retort, asthe heat at that point will cause the disintegration of said residuumand permit the false bottom and the bricks adhering to it to be liftedby a hook introduced through the manhole a in the part A of the. retort,the eye j in the bottom J being provided for that purpose and to betaken out through the manhole, for which reason the man-hole should bemade as large as practicable for the purpose of allowing the easypassage of the mass of bricks with the false bottom attached. Afterbeing cleaned the brick and false bottom may be returned and placed intheir proper rela tive positions.

The oil flowing over the surface of the brick and being, as hereinbeforementioned, graduallyheated to the point of decomposition will, whendecomposed thereby, produce more gas and a much more reliable qualitythan would be otherwise obtained. Hence I prefer bricks or someanalogous material for use on the false bottom.

The part B of the furnace is provided with an outlet-pipe, h, as shown.The man-hole a is of comparatively small size, as shown, for the reasonthat through it the false bottom J sufficient distance from the retortto insure against the transmission of sufficient heat to the reservoirthrough said pipe I) to vaporize the oil therein.

Having" thus described myinvention, whatI claim as new, and desire tosecure by Letters Patent of the United States, is-

In an apparatus for generating gas from petroleum-oil, a retort having afalse bottom J, said false bottom having a hook attached to its edge tobe used in withdrawing said bottom from the retort, and the bricks K,carried by said false bottom adapted to be attached to the same by theresiduum from the petroleum-oil, substai'ltially as and for the purposeset forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

AUGUST XVEYER.
